What are frames and scripts in “Artificial Intelligence”?

Frames are a variant of semantic networks which is one of the popular ways of presenting non-procedural knowledge in an expert system. A frame which is an artificial data structure is used to divide knowledge into substructure by representing “stereotyped situations’. Scripts are similar to frames, except the values that fill the slots must be ordered.  Scripts are used in natural language understanding systems to organize a knowledge base in terms of the situation that the system should understand.

What Is The Difference Between Strong Ai And Weak Ai?

Strong AI makes the bold claim that computers can be made to think on a level (at least) equal to humans. Weak AI simply states that some “thinking-like” features can be added to computers to make them more useful tools… and this has already started to happen (witness expert systems, drive-by-wire cars and speech recognition software). What does ‘think’ and ‘thinking-like’ mean? That’s a matter of much debate.

I Am A Programmer Interested In Ai. I Am Writing A Game That Needs Ai. Where Do I Start?

It depends what the game does. If it’s a two-player board game,look into the “Mini-max” search algorithm for games. In most commercial games, the AI is is a combination of high-level scripts and low-level efficiently-coded, real-time, rule-based systems. Often, commercial games tend to use finite state machines for computer players. Recently, discrete Markov models have been used to simulate unpredictible human players (the buzzword compliant name being “fuzzy” finite state machines).

A recent popular game, “Black and White”, used machine learning techniques for the non-human controlled characters. Basic reinforcement learning, perceptrons and decision trees were all parts of the learning system.

What Is An Agent?

A very misused term. Today, an agent seems to mean a stand-alone piece of AI-ish software that scours across the internet doing something “intelligent.” Russell and Norvig define it as “anything that can can be viewed a perceiving its environment through sensors and acting upon that environment through effectors.” Several papers I’ve read treat it as ‘any program that operates on behalf of a human,’ similar to its use in the phrase ‘travel agent’. Marvin Minsky has yet another definition in the book “Society of Mind.” Minsky’s hypothesis is that a large number of seemingly-mindless agents can work together in a society to create an intelligent society of mind. Minsky theorizes that not only will this be the basis of computer intelligence, but it is also an explanation of how human intelligence works. Andrew Moore at Carnegie Mellon University once remarked that “The only proper use of the word ‘agent’ is when preceded by the words ‘travel’, ‘secret’, or ‘double’.”

What Has Ai Accomplished?

Quite a bit, actually. In ‘Computing machinery and intelligence.’, Alan Turing, one of the founders of computer science, made the claim that by the year 2000, computers would be able to pass the Turing test at a reasonably sophisticated level, in particular, that the average interrogator would not be able to identify the computer correctly more than 70 per cent of the time after a five minute conversation. AI hasn’t quite lived upto Turing’s claims, but quite a bit of progress has been made, including:

  • Deployed speech dialog systems by firms like IBM, Dragon and Lernout & Hauspie
  • Financial software, which is used by banks to scan credit card transactions for unusual patterns that might signal fraud. One piece of software is estimated to save banks $500 million annually.
  • Applications of expert systems/case-based reasoning: a computerized Leukemia diagnosis system did a better job checking for blood disorders than human experts.
  • Machine translation for Environment Canada: software developed in the 1970s translated natural language weather forecasts between English and French. Purportedly stil in use.

What Are The Branches Of Ai?

There are many, some are ‘problems’ and some are ‘techniques’.

Automatic Programming: The task of describing what a program should do and having the AI system ‘write’ the program.

Bayesian Networks: A technique of structuring and conferencing with probabilistic information. (Part of the “machine learning” problem).

Constraint Satisfaction: solving NP-complete problems, using a variety of techniques.

Knowledge Engineering/Representation: turning what we know about particular domain into a form in which a computer can understand it.

Machine Learning: Programs that learn from experience or data.

Natural Language Processing(NLP): Processing and (perhaps) understanding human (“natural”) language. Also known as computational linguistics.

Neural Networks(NN): The study of programs that function in a manner similar to how animal brains do.

Planning: given a set of actions, a goal state, and a present state, decide which actions must be taken so that the present state is turned into the goal state

Robotics: The intersection of AI and robotics, this field tries to get (usually mobile) robots to act intelligently.

Speech Recognition: Conversion of speech into text.

What Are Good Programming Languages For Ai?

This topic can be somewhat sensitive, so I’ll probably tread on a few toes, please forgive me. There is no authoritative answer for this question, as it really depends on what languages you like programming in. AI programs have been written in just about every language ever created. The most common seem to be Lisp, Prolog, C/C++, recently Java, and even more recently, Python.

LISP: For many years, AI was done as research in universities and laboratories, thus fast prototyping was favored over fast execution. This is one reason why AI has favored high-level languages such as Lisp. This tradition means that current AI Lisp programmers can draw on many resources from the community. Features of the language that are good for AI programming include: garbage collection, dynamic typing, functions as data, uniform syntax, interactive environment, and extensibility. Read Paul Graham’s essay, “Beating the Averages” for a discussion of some serious advantages:

PROLOG: This language wins ‘cool idea’ competition. It wasn’t until the 70s that people began to realize that a set of logical statements plus a general theorem prover could make up a program. Prolog combines the high-level and traditional advantages of Lisp with a built-in unifier, which is particularly useful in AI. Prolog seems to be good for problems in which logic is intimately involved, or whose solutions have a succinct logical characterization. Its major drawback (IMHO)

What Is The Difference Between Classical Ai And Statistical Ai?

Statistical AI, arising from machine learning, tends to be more concerned with “inductive” thought: given a set of patterns, induce the trend. Classical AI, on the other hand, is more concerned with “deductive” thought: given a set of constraints, deduce a conclusion. Another difference, as mentioned in the previous question, is that C++ tends to be a favorite language for statistical AI while LISP dominates in classical AI.

A system can’t be truly intelligent without displaying properties of both inductive and deductive thought. This lends many to believe that in the end, there will be some kind of synthesis of statistical and classical AI.

What Are Best Graduate Schools For Ai?

  • The short answer is: MIT, CMU, and Stanford are historically the powerhouses of AI and still are the top 3 today.

    There are however, hundreds of schools all over the world with at least one or two active researchers doing interesting work in AI. What is most important in graduate school is finding an advisor who is doing something YOU are interested in. Read about what’s going on in the field and then identify the the people in the field that are doing that research you find most interesting. If a professor and his students are publishing frequently, then that should be a place to consider.

What Are Partial, Alternate, Artificial, Compound And Natural Key?

It is a set of attributes that can uniquely identify weak entities and that are related to same owner entity. It is sometime called as Discriminator.

Alternate Key:

All Candidate Keys excluding the Primary Key are known as Alternate Keys.

Artificial Key:

If no obvious key, either stand alone or compound is available, then the last resort is to simply create a key, by assigning a unique number to each record or occurrence. Then this is known as developing an artificial key.

Compound Key:

If no single data element uniquely identifies occurrences within a construct, then combining multiple elements to create a unique identifier for the construct is known as creating a compound key.

Natural Key:

When one of the data elements stored within a construct is utilized as the primary key, then it is called the natural key.

  2. Knowledge should be represented such that it should be understood by the people who have provided it
  3. Knowledge should be represented in a way that it can be easily modified
  4. Knowledge should be represented such that it should still be applicable to one or more situations even if it is inaccurate or incomplete

How Many Types Of Entities Are There In Knowledge Representation?

  4. Acquisitional Efficiency: It must be able to incorporate new information

What Are The Techniques To Represent Knowledge?

There are four techniques to represent knowledge:

  1. Relational knowledge: In this representation, knowledge is represented as a set of relations, similar to relations that are used in the database
  2. Inheritable knowledge: In this representation, knowledge is represented using objects, their attributes and the values of the attributes
  3. Inferential knowledge: In this representation, knowledge is represented in the form of first-order predicate logic
  4. Procedural knowledge: In this representation, knowledge is represented as a set of rules and a rule describes an action to be performed when a condition is met

What Is Relational Knowledge?

It is a knowledge representation scheme in which facts are represented as a set of relations. For example knowledge about players can be represented using a relation called “player” having three fields: player name, height and weight. This form of knowledge representation provides weak inferential capabilities when used as standalone but are useful as an input for sophisticated inferential procedures.

What Is Inheritable Knowledge?

It is a knowledge representation scheme in which knowledge is represented using objects, their attributes and corresponding value of the attributes. The relation between different objects is defined using a “isa” property. For example if two entities “Adult male” and “Person” are represented as objects then the relation between the two is that Adult male “isa” person.

What are the steps followed in a system which attempts to solve a given problem?

A system must do the following in order to solve a particular problem:

a) It should define the problem accurately by specifying the initial situation and final situation (solution of the problem)

b) It should analyze the problem thoroughly because if an important feature is skipped, the technique employed to solve the problem may become ineffective

What is a state space of a problem?

It is a set of states where each state represents a legal position within the problem. A state space must contain an initial state and a set of final states representing set of acceptable states. Using a set of rules, one of final states can be reached from the initial state. For example, in chess there exists a set of states where each state represents a legal board position and rules are used to reach one of the final states from the start state.

What is the benefit of representing a problem using a state space?

There are two benefits of representing a problem using a state space:

a) As most AI problems require transition from a given situation (initial state) to a desired situation (final state), a state space defines these problems formally

b) It helps in solving the problem using a set of rules and search. Search is considered as an important technique because it helps in solving difficult problems in the absence of direct techniques.

What do you mean by the term “operationalization”?

It is the process of converting an informal description of a problem into a formal description. This process is easy for problems which are not natural and are highly structured such as water-jug and chess problems. But this process is difficult for natural occurring problems such as understanding an English sentence where this process may be automated using programs.

What are the steps followed in order to provide a formal description of a problem?

In order to provide a formal description of a problem the full steps should be followed:

a) Define a state space. A state space may be defined without explicitly specifying all of its states

b) Define one or more states that may represent possible situations from which the process of problem-solving may start. These states are known as initial states

c) Define one or more states that may represent situations which are considered as acceptable solutions to the problem. These states are known as final or goal states

d) Define various actions to be performed. These are known as set of rules

What are the components of a production system?

A production system is composed of following:

a) A set of rules: A rule consists of two parts: a left side and a right side. Left side of the rule denotes condition of the rule and the right side denotes the action to be taken when the condition is met

b) One or more knowledge database: A knowledge database contains all the information required for problem solving process. It is important to note that all parts of knowledge database may not be relevant to the solution of the problem

c) A control strategy: A control strategy specifies the sequence in which the rules will be compared against the knowledge database in order to be applied. A control strategy also resolves the conflict when more than one rule matches

d) A rule applier: It is a system which applies the rule by using a control strategy
